TING FEED-ROLLS.

To aZZ whom it may concern.-

Be it known that I, LEONARD KISSNER, of Lancaster, in the county of Fairfield and State of Ohio, have invented certain new and useful Feed-Rolls for Straw-Gutters; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to means for operating feed-rolls for straw-cutters.

Prior to myinvention one of a pair of feedand provided with a universal joint attached to one end of its shaft and to a rocking pinion which was adapted to engage a pinion on the end of the shaft of the stationary roll. With such a construction, when the gear-wheels move out of a vertical plane, there is an undue wearing and cutting of the cogs when the machine is in motion, thus causing the parts to become impaired in a short time.

It is the object of my present invention to vice that the driving-pinions are always kept in a vertical plane, while one of the feed-rolls is permitted to have a rising-and-falling mo-- bit}? in its hearing at either or both ends of the ro lVith this object in view my invention consists in certain novel features of construction and peculiar combinations and arrangements of parts, as will be hereinafter set forth, and pointed out in the claim.

In the accompanying drawings, Figure l is a side elevation of a pair of rolls having my improvements applied thereto. Fig. 2 is a similar view with the adjustable roll in the reverse position. Fig. 3 is a view of the universal joints and connecting-rod detached.

A represents a portion of the frame-work of a straw-cutter havingafeed-roller, B, mounted in fixed bearings therein. The shaft B of this roller is extended horizontally somewhat beyond the frame A and provided at or near its free end with a pinion, (1.

Immediately beneath the roller Bis another roller, G, mounted in sliding bearings, suit-able springs, to, being provided beneath the journals of this roll to yieldingly retain the two rolls in their normal position,or in.contact,and permit the lower roll to yield when a hard unyielding substance passes between them.

It will of course be seen that instead oi'journaling the movable roll beneath the roll in fixed bearings the reverse arrangement may be adopted with equal advantage, as it is simply a matter of choice which roll shall be above and which below.

In order to drive or rotate the movable roll while the machine is in operation without affecting the relative arrangement of the gearing, I connect the shaft of said movable roll with its driving-pinion b by means of two universal joints, D D, and an interposed connecting-rod, E.

The universal joints I) D will preferably be made of the usual form, comprising two collars, c 0, having ears (1, each collar being pivotally connected to a central disk at two points; or these joints D may be of any other desired construction. The head 0 of one collar c of each of the universal joints is provided with a preferablysquare or angularperforation, e, for the reception of thesquared or angular end of the connecting-rod E. The connectingrod E is adapted to have a sliding movement in one or both of the joints D, as

one or the other end of its attached roll is elevated or lowered by the. passage between them of more material at one end than at the other. The rod E will be provided at its ends with suitable retaining-pins to prevent it from becoming detached from the joints D. Thus it will be seen that when more material passes between the rolls at one end than at the other one roll will be forced away from the other, and at the same time will continue its revolutions and feed more material through the rolls without changing the relative position of the driving mechanism. This is a very important feature in the construction of feed-cutters, and is very effectually accomplished by providing two universal joints between the movable roll and its drivingpinion, and connecting these joints by means of a rod having a sliding connection with the joints, as above explained.

Slight changes might be made in the constructive details of my invention without departing from the spirit thereof or limiting its scope; hence I do not wish to limit myself to the exact details of construction herein set a universal joint at one end, and an angular forth; but, bar adapted to have a sliding connection in Having fully described my invention, what I the -angular openings of said universal joints, 1 claim as new, and desire to secure by Letters substantially as set forth. 5 Patent, is In testimony whereof I have signed this The combination, with a roller journaled in specification in the presence of two subscribfixed bearings and having a shaft extending ing witnesses.
